Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0033] Example 1

[0034] This embodiment provides a storage device for hemodialysis puncture needles, such as... Figure 1 As shown, it includes a box body 1, a first limiting member 2, and a second limiting member 3.

[0035] like Figure 1 and Figure 2 As shown, the box 1 includes a body 11 and a receiving groove 12; the receiving groove 12 has a T-shaped groove with an opening at the top for accommodating the puncture needle 7. The receiving groove 12 includes a needle tube groove 121, a butterfly wing groove 122 and a retaining groove 123; one end of the needle tube groove 121 is closed and the other end is connected to one end of the butterfly wing groove 122; the retaining groove 123 is a U-shaped through groove, one end of which is connected to the other end of the butterfly wing groove 122, for accommodating the part where the rigid tube 73 of the puncture needle is connected to the flexible tube 74.

[0036] like Figure 1 and Figure 2 As shown, the needle groove 121 is a straight groove, and its length matches the length of the needle 71. Considering that when the puncture needle 7 is withdrawn, the medical staff will hold the flexible tube 74 behind the butterfly wing 72, the width of the needle groove 121 needs to be several times the diameter of the needle 71 in order to allow the needle 71 to enter the needle groove 121 smoothly; for example, the width of the needle groove 121 is 10-20mm.

[0037] like Figure 1 and Figure 2 As shown, the planar profile of the butterfly wing groove 122 matches the planar profile of the butterfly wing 72 so that the butterfly wing 72 can be placed stably in the butterfly wing groove 122.

[0038] like Figure 1 and Figure 2 As shown, the slot 123 is located at the center of the rear end face of the body 11, and its width matches the diameter of the hose 74. Since the butterfly wing 72 has a rigid tube 73 at its center, one end of the rigid tube 73 can be inserted into the slot 123 after being connected to the hose 74, thereby fixing the position of the puncture needle 7 in the receiving groove 12.

[0039] like Figure 1 and Figure 2 As shown, the first limiting member 2 is located in the middle section of the opening above the needle groove 121, and is used to block the needle 71 inside the needle groove 121.

[0040] like Figure 1 and Figure 2 As shown, the first limiting member 2 includes a first baffle 21 and a second baffle 22; the first baffle 21 and the second baffle 22 are symmetrically arranged on both sides of the longitudinal symmetry plane of the needle groove 121. One end of the first baffle 21 and the second baffle 22 are respectively fixed on the side wall of the body 11 on both sides of the needle groove 121, and the other end extends into the needle groove 121 and fits against each other.

[0041] like Figure 1 and Figure 2 As shown, the distance between the bottom surface of the first baffle 21 and the second baffle 22 and the bottom surface of the needle groove 121 is at least greater than the radius of the tubing, so that the puncture needle 7 can be laid flat in the receiving groove 12.

[0042] The first baffle 21 and the second baffle 22 are made of elastic materials, such as medical plastic. When the needle tube is above the first baffle 21 and the second baffle 22 and subjected to downward pressure, the first baffle 21 and the second baffle 22 can undergo elastic deformation under the pressure of the needle tube 71, so that there is a gap between the first baffle 21 and the second baffle 22, thereby allowing the needle tube 71 to be pressed into the needle tube groove 121, thereby achieving the limiting.

[0043] In some embodiments, the thickness of the end of the first baffle 21 and the second baffle 22 that abuts is less than the thickness of the end of the body 11, so that the needle tube 71 can be easily pressed into the needle tube groove 121, and the first baffle 21 and the second baffle 22 can maintain contact and are less likely to produce gaps.

[0044] like Figure 1 and Figure 2 As shown, the second limiting member 3 is located at the opening of the butterfly wing groove 122 and is used to partially block the upper part of the butterfly wing 72 inside the butterfly wing groove 122.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the second limiting member 3 consists of two symmetrically arranged plates, one end of which is fixed to the side wall of the body 11 and the other end extends into the butterfly wing groove 122. For example, the width of the second limiting member 3 extending into the butterfly wing groove 122 is 3-5 mm, so that the soft silicone butterfly wing 72 can be pressed into the butterfly wing groove 122, thereby working together with the second limiting member 3 to block and limit the puncture needle 7, preventing the puncture needle 7 from accidentally slipping out of the receiving groove 12.

[0046] In use, first place the storage device for the hemodialysis puncture needle of this embodiment on the patient's arm. The medical staff presses the puncture needle inlet on the patient's arm with one hand and pinches the tubing 74 with the other hand to pull the puncture needle 7 out of the patient's body. Then, quickly move the puncture needle 7 above the receiving groove 12 and press the hard tube 73 down with your fingers so that the needle tube 71 breaks through the first limiting member 2 and enters the needle tube groove 121. The butterfly wing 72 is deformed by the compression of the second limiting member 3 and enters the butterfly wing groove 122. Finally, the part where the hard tube 73 and the tubing 74 are connected is locked in the slot 123, completing the storage and fixation of the puncture needle 7 in the storage device.

[0047] The needle storage device in this embodiment does not require a large storage space and can be quickly stored with one hand. The needle is in a stable position, and the storage effect is safe and reliable, effectively avoiding the risk of needle puncture and secondary contamination.

[0048] Considering that two puncture needles 7 need to be removed for each patient, preferably, the height of the receiving groove 12 is greater than the height of the two puncture needles 7 stacked together, so that one patient can use one of these storage devices, improving efficiency and saving resources.

[0049] Example 2

[0050] The difference between the hemodialysis puncture needle storage device in this embodiment and that in embodiment 1 is that the adjacent ends of the first baffle 21 and the second baffle 22 overlap vertically.

[0051] Given the thinness of the needle tube 71, when the puncture needle 7 is located within the receiving groove 12, if there is a gap between the first baffle 21 and the second baffle 22, the puncture needle 7 may still accidentally detach from the receiving groove 12. Therefore, as Figure 3 As shown, in this embodiment, the first baffle 21 and the second baffle 22 are arranged with their adjacent ends overlapping vertically, so that the contact surfaces of the first baffle 21 and the second baffle 22 are not in the vertical direction, thereby effectively preventing the puncture needle 7 from accidentally coming out of the receiving groove 12.

[0052] Example 3

[0053] The difference between the hemodialysis puncture needle storage device of this embodiment and those of Embodiments 1 and 2 is that it also includes a third limiting member 4.

[0054] like Figure 4 As shown, the third limiting member 4 is located at the end of the opening above the needle groove 121, and is used to limit and block the tip of the puncture needle 7. For example, the third limiting member 4 includes a baffle located above the sealed end of the needle groove 121.

[0055] Because the flexible tube 74 of the puncture needle 7 contains blood, the needle tip tends to curl upwards when the puncture needle 7 is pulled out and laid flat. Additionally, the needle tip also tends to curl upwards when the connection between the rigid tube 73 and the flexible tube 74 is engaged in the slot 123. This embodiment, by providing a third limiting member 4, not only limits the needle tip when it curls upwards, but also prevents the blood remaining at the needle tip from flowing out of the container or splashing onto medical personnel, thus preventing contamination.

[0056] In some embodiments, such as Figure 4 As shown, the bottom of the receiving tank 12 is also provided with a liquid-absorbing pad 5. The liquid-absorbing pad 5 is fixed on the bottom plane of the receiving tank 12 and is made of absorbent material so as to absorb the small amount of blood flowing out from the needle tube 71 and prevent secondary pollution caused by flowing out during the storage of the puncture needle 7 or the recovery of the device.

[0057] Example 4

[0058] The difference between the hemodialysis puncture needle storage device in this embodiment and those in embodiments 1 to 3 is that it also includes a cover plate 6.

[0059] like Figure 5 As shown, in this embodiment, the cover plate 6 is rotatably connected to one side of the box body 1, and the rotation direction is around the center line of the needle tube groove 121, thereby achieving the coverage of the receiving groove 12.

[0060] Considering the lightweight nature of the needle storage device, when medical personnel hold the flexible tube 74 behind the butterfly wing 72 and place the needle 7 downwards with the needle tip aligned with the front end of the opening above the needle tube groove 121, the needle storage device is prone to movement, thus affecting the smooth insertion of the needle 7 into the receiving groove 12. For example... Figure 5 As shown, in this embodiment, the cover plate 6 is rotatably connected to one side of the bottom of the box body 1. The cover plate 6 is foldable and can be opened and closed. The cover plate 6 includes a side cover plate 61 and an upper cover plate 62 that can be folded together. The height of the side cover plate 61 matches the height of the box body 1, and the upper cover plate 62 can at least cover the upper opening of the receiving groove 12. When the cover plate 6 is opened, the side cover plate 61 and the upper cover plate 62 can be fully unfolded and flattened. By inserting the unfolded and flattened cover plate 6 into the bottom of the patient's arm, the patient's arm can be used to limit the storage device of the puncture needle, thereby effectively preventing the movement of the storage device of the puncture needle from affecting the storage process of the puncture needle, improving the efficiency of operation and the safety of the process.

[0061] In some embodiments, a snap-fit ​​structure is provided between the upper cover plate 62 and the upper end face of the box body 1. When the cover plate 6 is placed on the box body 1, the upper cover plate 62 can be locked on the box body 1 through the snap-fit ​​structure, thereby closing the puncture needle inside the box body 1, further improving the safety of the puncture needle 7 in the entire process.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
